This appeal primarily concerns the issue of whether a defendant’s perjury before a grand jury was “in respect to a criminal offense” for purposes of the sentencing enhancement required by section 2J1.3(c)(l) of the Sentencing Guidelines. The United States appeals from the November 25, 1998, judgment of the District Court for the Southern District of New York (Whitman Knapp, District Judge), which imposed a sentence of ten months (time served) on Ibrahim Ahmad Suleiman, after he was found guilty of perjury in violation of 18 U.S.C. § 1623 (1994). In determining the sentence, Judge Knapp declined to increase Suleiman’s offense level by the enhancement that section 2J1.3(c)(l) would have required,, if applicable. We conclude that the enhancement was required, but, because Suleiman has been deported and cannot now be present for resentencing, we dispose of the Government’s appeal by affirming the judgment, without prejudice to an application by the Government to the District Court to resentence Suleiman in the event he becomes available for resentencing. The issues raised by Suleiman’s cross-appeal, which challenge his conviction, have been disposed of in a summary order filed today.
Background
On February 26, 1993, a bomb exploded at the World Trade Center in New York City, killing several people and injuring hundreds. Soon thereafter, a grand jury in the Southern District of New York began investigating the bombing. In September 1993, the grand jury issued indictments against Ahmad Mohammed Ajaj, Ramzi Ahmed Yousef, and others on various charges relating to their participation
*35
in the plot to bomb the World Trade Center, including a charge of conspiracy to damage and destroy a building in violation of 18 U.S.C. § 844(i). Ajaj and various co-conspirators were convicted in March 1994.
See United States v. Salameh,
On February 27, 1996, defendant-appel-lee Ibrahim Ahmad Suleiman was served with subpoenas in San Antonio, Texas, to appear before the grand jury in New York. An FBI agent explained to Suleiman that the grand jury sought to question him because “the information and the actual trial information from specifically Mohammed Ajaj and the World Trade Center bombing” indicated that Suleiman had traveled with Ajaj from Houston to Pakistan and “we wanted to find out what the circumstances were that he traveled with Mr. Ajaj.”
On April 3, 1996, Suleiman testified before the grand jury. After Suleiman had stated his name, the Assistant United States Attorney (“AUSA”) explained, “The grand jury is investigating violations of Title 18, United States Code, Section 371 and Section 844. Section 371 is a conspiracy statute and Section 844 relates to bombing of buildings used in interstate commerce.” The AUSA added that the grand jury also had the power to indict for other federal crimes uncovered in the course of its investigation. Suleiman was informed of his constitutional privilege against self-incrimination and then questioned.
On October 28, 1996, the grand jury indicted Suleiman on three counts of perjury in violation of 18 U.S.C. § 1623. The indictment asserted that the grand jury’s investigation focused in part on the origin of the relationship between Yousef and Ajaj. In particular, the indictment alleged that it was material that the grand jury ascertain, among other things, (1) why Ahmad Ajaj traveled from Houston, Texas, to Peshawar, Pakistan, in the spring of 1992; (2) the names of persons who accompanied Ajaj during his travels from Houston, Texas, to Peshawar, Pakistan, in the spring of 1992 and the reasons why they accompanied Ajaj; (3) the names of persons with whom Ajaj associated and traveled while in Pakistan and Afghanistan; (4) how Ajaj came to possess false documentation and manuals relating to bombs and other explosive devices; and (5) how Ajaj came to meet Yousef.
The indictment alleged three counts of perjury. Count One specified that Suleiman committed perjury when he testified that he intended to travel alone, made plans to travel alone, and actually did travel alone to Pakistan in April 1992, and that he did not know, or make any flight reservations with, a person named Muhammed Gihad Abid. Count Two alleged, among other things, that Suleiman committed perjury by testifying that he had never seen, nor seen Ajaj in possession of, various documents, including four large blue manuals containing information about making explosives. These manuals, which had been seized from Ajaj, bore Suleiman’s fingerprints. Count Three alleged that Suleiman had committed perjury because, when presented with a photo of Yousef, he testified that he had never seen the person before. The trial jury found Suleiman guilty of all eleven specifications in the first perjury count, and twelve of the eighteen specifications in the second perjury count. The jury could not reach a verdict on Count Three.
At a sentencing hearing on November 1, 1998, the Government argued that Suleiman committed perjury “in respect to a criminal offense” under U.S.S.G. § 2J1.3(e)(l) (1998). Suleiman, however, argued that the perjury was not “in re
*36
spect to” the conspiracy to bomb the World Trade Center because he was never directly questioned about his involvement in that bombing. Sentencing was continued until November 24, at which time Judge Knapp, declining to make the section 2J1.3(c)(l) enhancement, sentenced Suleiman to ten months in prison (time served). Judgment was entered on November 25. After the sentencing, Judge Knapp issued an order explaining his decision not to add the enhancement. He characterized the case as one “where neither the questions asked nor the answers given referenced any criminal offense,” and concluded, “[W]e adhere to our finding of fact that none of the defendant’s con-eededly false statements were uttered ‘in respect to a criminal offense.’ ”
United States v. Suleiman,
Suleiman has served his prison term and has been deported.
Discussion
I. Mootness
We consider
sua sponte
whether Suleiman’s completion of his prison sentence or his subsequent deportation have rendered this appeal moot.
See Fox v. Board of Trustees,
We first consider the significance of Suleiman’s completion of his sentence. “A criminal case does not necessarily become moot when the convict finishes serving the sentence. Instead, the case will remain a live case or controversy if there exists ‘some concrete and continuing injury’ or ‘collateral consequence’ resulting from the conviction.”
United States v. Mercurris,
Our Court, however, has rejected the reasoning in
Soto-Holguin,
in light of the Supreme Court’s decision in
Spencer,
Although the prospect that an enhanced sentence might affect some subsequent prosecution is too remote to avoid mootness, the issue remains whether mootness is avoided by the prospect of imposing an enhanced sentenced on Suleiman in the pending case. No question of mootness would arise if Suleiman were still in this country, available to be resentenced should the Government succeed on the merits of this appeal. 3
The mootness issue is complicated, however, by the fact that Suleiman has not only served his sentence but also been deported. We recently ruled that a defendant’s completion of his prison term and his subsequent deportation mooted
his
appeal of the sentence,
see Mercurris,
Although
Villamonte-Marquez
involved an appeal to reinstate convictions, not an appeal to increase a sentence already served, we have applied the reasoning of that decision to rule that where a defendant had completed his term of incarceration but continues to serve his term of supervised release, his deportation did not moot the Government’s appeal of his sentence.
See United States v. Londono,
Similarly, if Suleiman voluntarily returns to the United States or is extradited, the Government could arrest him and require him to serve out the term of a longer sentence. Though arguably speculative, the possibilities of extradition or re-entry into the United States are precisely the kind of circumstances recognized in
Villa-monte-Marquez
and
Londono
as preventing deportation from mooting a Government criminal appeal seeking an enhanced sentence.
See Valdez-Gonzalez,
II. The Merits
The issue on the merits is whether Suleiman committed perjury “in respect to” a criminal offense within the meaning of U.S.S.G. § 2J1.3(c)(l). Section 2J1.3 provides a base offense level of 12 for perjury. See U.S.S.G. § 2J1.3(a). That section also provides, “If the offense involved perjury ... in respect to a criminal offense, apply § 2X3.1 (Accessory After the Fact) in respect to that criminal offense, if the resulting offense level is greater than that determined above.” Id. § 2J1.3(c)(l). In turn, section 2X3.1 sets the base offense level for an accessory after-the-fact at “6 levels lower than the offense level for the underlying offense,” with a minimum of 4 and a maximum of 30, id. § 2X3.1(a), and instructs the sentencing judge to apply the base level offense for the underlying offense “plus any applicable specific offense characteristics that were known, or reasonably should have been known, by the defendant,” id. § 2X3.1, comment, (n.l). In Suleiman’s case, the enhanced offense level would have been 30, 4 and the resulting sentencing range would have been 97 to 121 months, limited by the ten-year aggregate statutory maximum for the two perjury counts.
Although the Sentencing Commission defined “underlying offense” in section 2X3.1 to mean “the offense as to which the defendant is
convicted
of being an accessory,”
id.
(emphasis added), the defendant need not have been convicted for participating in the underlying offense for section 2J1.3(c)(l) to apply,
see United States v. Gay,
For section 2J1.3(c)(l) to apply, however, a defendant’s perjury must be “in respect to” a criminal offense, a requirement we have previously considered. In
Gay,
In this case, although the crime of conspiracy to bomb the World Trade Center has unquestionably been committed, the District Court characterized this case as one “where neither the questions asked nor the answers given referenced any criminal offense,”
Suleiman,
We review
de novo
a district court’s interpretation of the Sentencing Guidelines,
see United States v. Shepardson,
Typically, “[t]he issues before a grand jury ... are not predetermined. Its function is to investigate possible crimes against the sovereign so that it can make a judgment whether a trial on specific charges is necessary. The scope of legitimate inquiry is therefore broad....”
United States v. Mancuso,
The evidence indisputably establishes that Suleiman understood that the grand jury was investigating a criminal offense— the World Trade Center bombing. An FBI agent had explained to Suleiman that the grand jury sought to question him because “the information and the actual trial information from specifically Mohammed Ajaj and the World Trade Center bombing led us to determining that Mr. Suleiman had traveled with Mohammed Ajaj from Houston, Texas to Pakistan with a stop in New York and we wanted to find out what the circumstances were that he traveled with Mr. Ajaj.” On the day of the testimony, the AUSA explained to Suleiman that the grand jury was investigating violations of statutes concerning conspiracy and the bombing of buildings used in interstate commerce. We conclude that Suleiman committed perjury “in respect to a criminal offense” under section 2J1.3(c)(l), and that the sentencing enhancement derived from the offense of conspiracy to bomb the World Trade Center should have been applied.
III. The Remedy
Under normal circumstances, we would vacate the sentence originally imposed and remand for resentencing pursuant to Fed.R.Crim.P. 35(a)(1). Suleiman’s deportation, however, makes it impossible for the District Court now to resentence in accordance with Rule 43(a) of the Federal Rules of Criminal Procedure, which requires the defendant to be present “at the imposition of-sentence, except as otherwise provided by this rule.” Fed.R.Crim.P. 43(a). Although Rule 43 allows for sentencing under certain conditions where the defendant is “voluntarily absent at the imposition of sentence,” Fed.R.Crim.P. 43(b)(2), that exception does not apply to Suleiman because a deportee by definition does not voluntarily leave the country. 5
*41 Since resentencing now is not available, the normal remedy of vacating the sentence and remanding for resentencing has the potential for undesirable and even mischievous results. Such a remand would leave the case for perhaps an extended period of time in the jurisdictional limbo of the District Court’s suspense calendar, and during that interval, the defendant would be able to assert that the sentence previously imposed has been vacated. To avoid these consequences, we will affirm the judgment of the District Court but do so without prejudice to an application by the Government to the District Court to vacate that judgment and resentence Suleiman in accordance with this opinion within 90 days after such time, if ever, as the Government knows or reasonably should know that Suleiman is in this country and available for resentencing in accordance with Fed.R.Crim.P. 43.
Conclusion
The judgment is affirmed, without prejudice to a subsequent motion by the Government to increase the sentence pursuant to section 2J1.3(c)(l) of the Sentencing Guidelines.
Notes
. In
United States v. Londono,
. Although rejecting the view that the .prospect of a future prosecution and sentencing would save from mootness the Government's appeal of a sentence already served, the Tenth Circuit in
Meyers
advanced a different rationale for entertaining such an appeal: the Government’s “remediable injury’’ arising from "the trial court’s failure to impose the appropriate sentence pursuant to statute or the sentencing guidelines.”
.We express no view as to whether a Government appeal seeking to impose additional jail time on a defendant who has already completed his sentence implicates the Double Jeopardy Clause, because neither party has raised the issue.
Cf. United States v.. Rico,
. It is undisputed that the underlying offense is conspiracy to damage or destroy a building in which six people were killed, and that this offense carries an offense level of 43. Section 2X3.1 specifies a level six levels below that level, or 37, but also specifies a maximum offense level of 30.
. Nor is the need for the defendant’s presence eliminated by Rule 43(c), which states that a defendant "need not be present ... when the proceeding involves a reduction or correction of sentence under Rule 35(b) or (c) or 18 U.S.C. § 3582(c).” Fed.R.Crim.P. 43(c)(4). Rule 43(c) does not apply to Suleiman. See Fed.R.Crim.P. 43 advisory committee’s note to 1998 amendments ("As amended, Rule 43(c)(4) would permit a court to reduce or correct a sentence under Rule 35(b) or (c), respectively, without the defendant being present. But a sentencing proceeding being conducted on remand by an appellate court under Rule 35(a) would continue to require the defendant’s presence.”). Neither Rule 35(b), which governs the reduction of a sentence for substantial assistance, see Fed. R.Crim.P. 35(b), nor Rule 35(c), which authorizes a court to correct a sentence “imposed as a result of arithmetical, technical, or other clear error” within seven days after the imposition of the sentence, Fed.R.Crim.P. 35(c), applies here. The provisions of 18 U.S.C. *41 § 3582(c) also do not apply to the circumstances of this case.
